GRAIN-DOOR.

Specification of Letters Patent.

llatented Sept. 23, 191.3.

Application filed June 7, 1912. Serial No. 702,279.

To (ZZZ whom it may concern.

Be it known that I, Pn'rnn J. I-IANsnN, a citizen of the United States, residing at Lansford in the county of Bottinean and State of North Dakota, have invented new and useful Improvements in Grain-Doors, of which the following is a specification.

This invention relates to improvements in doors for grain cars.

In carrying out my invention it is my purpose to provide a double door made up in sections so that the joints between the inner sections of the door are over-lapped by the outer sections of the door and thus provide a substantially solid door wherein leaking of the grain through the door is clearly obviated.

I also aim to provide a door of this character wherein the lower sections may be removed from the outside of the car withoutinterfering with the upper sections of the door, thus permitting of a quantity of grain being removed from the car before the entire door is taken from the car.

It is a further object of my invention to provide a novel construction of locks for the sectional doors wherein the employment of springs, bolts or analogous retaining elements is dispensed with.

With the above recited objects in view and others which will appear as the nature of the invention is more fully understood, the improvement resides in the novel construction, combination and operative arrangement of parts set forth in and falling within the scope of the appended claims.

In the drawings,,Figure 1 is a front elevation of a car provided with the improved door. Fig. 2 is a similar view illustrating the lower sections of the door removed. Fig. 3 is a vertical sectional view upon the line 33 of Fig. 1. Fig. 4 is a horizontal sectional view upon the line l-4= of Fig. 1. Fig. 5 is a similar sectional view upon the line 5-5 of Fig. 1. Fig. 6 is an elevation looking toward the door from the interior of the ear. Fig. 7 is a perspective View of one of the sections of the outer door member. Fig. 8 is a similar view of one of the wedgeshaped locking blocks. Fig. 9 is a similar View of one of the fillin blocks. Fig. 10 is a perspective view looking toward one of the vertical stiles of the door way, the door being removed. Fig. 11 is a similar view looking toward the opposite vertical stile of the doorway.

Referring now to the drawings in detail, the numeral 1 designates an ordinary grain or freight. ear. The car has its side provided with the usual door opening. In the present instance one of the vcrtiial stiles for the door way or openiru and which is designated by the numeral 2 is provided with a centrally arranged vertically extending groove 3, and the said groove is preferably reinforced by a metallic plate 4. The inner face of this stile 2 is further pro vided with an L-shapcd member 5, the same being connected to the stile a distance away from the outer face of the said stile to provide a passage or Way ('1, thepurpose of which will presently be set forth. The opposite verti :al stile 7 provided for the doorway is recessed or grooved adjacent its inner face, as designated by the numeral 8, and the opening thus provided upon the inner face of the said stile is partially closed through the medium of a plate 9. This plate extends a slight distance beyond the edge of the stile 7 and has its extremity bent to provide a right angular or L-shaped member 10 which is adapted to form an abutment for the edges of the inner door sections 11 and 12, the opposite ends of the said sections being rounded and received Within the L-shaped passage or way (3 provided upon the stile 2. The members 11 and 12 are of an unequal width, the member 12 being of a less width than the member 11, and the said member being arranged below the member 1]. The outer face of each of the said members 11 and 19. are adapted to be contacted by the outer door sections l3 and 14. These door sections are also of unequal widths the lower section 14 is of a greater width than the upper section 13-3, and by this arrangeincnt it will be noted that the joints between the inner and outer sections are broken to provide lap joints, so that danger of the grain leaking through the opening is offectively obviated. One of the ends of each of the door sections 13 and l t is adapted to be received within the passage or way 8 of the stile 7, while the opposite edges abut against the portion 15 provided upon the stile 2 adjacent the groove 3. The ends of the door sections 13 and 14: received within the passage or way 8 of the stile 7 have their inner faces rounded. Both of the sections 13 and 14 are provided with resilient catch members 16 and 17, the same being secured upon the outer face of the said sections adjacent their edges which abut with the portion 15 of the stile 2. The catchrmembers 116 and 17 are each constructed of resilient material, being each provided with a substantially flat face which is secured to the sections 13 and 1 1 and being provided with an out-ward angular extension which. terminates in an inturned resilient angularly arranged base 16.

The numerals. 18 and 19 designate what I term filling blocks. Each of these blocks is of a length corresponding to the width or" each of the door sect-ions 13 and 1 and the said blocks are of a width greater than the depth of the groove 3 within which they are adapted to be received. The blocks are of a thickness equaling with the distance between the opposite walls provided by the said recess, and are adapted to frictionally engage with said walls. The portions of the blocks extending beyond the said groove contact with the faces of the door sections 13 and 14 adjacent the ends thereof which are arranged upon this side of the doorway.

The numerals 20 and 21 designate wedge blocks. Each of these wedge blocks is of a length corresponding with the height of the doorways 13 and 1 1-, one of which being provided for each of said doors, as is the case with the filling blocks 18 and 19. The wedge blocks from one of their faces beveled or inclined, and are adapted to be inserted between. the wedge blocks and the resilient inclinated face of the catch members whereby the face 16 of each of said set of sections also of unequal length are arranged to lap joints, and in order to remove the outer lower enlarged section 1a to permit of the removal of the lower reduced section 12-, an instrument or tool, such as a pry bar,is inserted between the upper and lower wedge blocks 20 and 21, so that the lower block may be forced outwardly from engagement with the resilient catch member 16 provided upon the door section 14. The door is, however, still retained within thedoorway by the filler block 18, and the pry bar is again employed for removing the said filler block. To aid in the removal of this block, the stile 2 is formed with a depression 22 which registers with a depression 23 in the said filler block, and which materially aids in the manipulation of the pry bar. When the filler wedge blocks'have been removed the door has its free end swung outwardlv at an angle, and is withdrawn from the passageway 8. The pressure of the contents of the car upon the inner and lower door section 12 (which has been relieved from contact by the door sec tion 1% materially assists in swinging the member 10 outwardl so that the opposite end thereof may be readily withdrawn from engagement within the passage or way 6. However, it the pressure of the contents of the car is not sutiicient to automatically swing the door outwardly, the pry bar may be again brought into use. In the mean time, it will be understood that the upper member of the inner section of the door is tightly compressed by the upperreduced section 13 of the outer member of the door, so that its angular removal is prevented. W hen it is desired to remove the upper secend of said door engaged by the L-shaped tions of both the inner and outer door meman outer set of sections also of unequal V widths arranged to lap oints, the inner set projecting beyond one side of the doorway and the outer set projecting beyond the other side of the doorway, means for preventing the inner set from inward movement in the ends whichdo not lap the doorway, and means for securing the opposite ends of the outer set in the doorway.

2. A door for grain cars or the like embodying two sets of independent members, one of said sets comprising a plurality of inner sections of unequal width, the outer set of sections also being of unequal width and arranged to lap joints, the inner set proj ecting beyond one side of the doorway and p the outer set projecting beyond the other side of the doorway, means for preventing the inner set from inward movement at the ends which do not overlap the doorway,

means for securing the opposite set within the doorway, said means embodying spring catch members arranged upon each of the sections, filler blocks arranged within one of the sides of the doorway, and wedge blocks arranged between the filler blocks 3 and the spring catch members. 7

3. A door for grain cars or the like comprising two sets of independent members,

one set comprising a plurality of inner sec tions of unequal width, and the outer set comprising a plurality of sections also of unequal width arranged to lap joints,one

of the stiles of the doorway having a depression to receive one of the ends of the outer sections of the door, the stiles of the door being provided with additional ways to receive the inner sections of the door, and to arrange one of the ends of said inner sections beyond one side of the doorway, the outer sections of the doorway not received within the depression of the stile each having a vertically arranged substantially V- shapcd resilient catch, the stile of the doorway adjacent the said catches being grooved, filler blocks of a size equaling the height of each of the outer sections Within the groove and projecting beyond the groove and engaging with the outer faces of the outer sections of the doorway, and Wedge blocks each oi. a size equaling the height of each of the outer sections oi. the doorway arranged between the tiller blocks and the spring 20 PETER JAMES HANSEN.
